To all whomz't may concern:

Be it known that l, MAURICE LACHMAN, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful llmprovements in Knockdown Containers, of which the f0llowing is a specification.

My present invention relates to shlpping receptacles or containers especially those 1n which the body portion is made of non-metallic material like paper, pulp or a similar substance.

The invention more particularly relates to such containers when made inknockdown form.

The main object of the invention is to provide a knockdown container or receptacle which will be cheap, light and uniform in Weight with other containers of the same style and size and at the same time provide a construction which can be quickly and easily assembled without any special tools being necessary. a

lit is a further object to maintain simplicity with rigidity and strength'in the assembled structure.

lln parts remote from manufacturing centers large orchards, mills, etc., are usually located and the expense of obtaining containers or receptacles of the. usual type in which to ship their goods is. very great owing to the bulk of the containers which are shipped to such places empty. Owlng to the increasing cost of lumber as well as the variation in weight, knockdown wooden barrels and boxes are fast becoming prohibitive while in knockdown metal containers the cost of the metal as well as its weight makes the use of this type very limited, all metal containers also being unsuitable for shipping many articles.

According to this invention the main body portion of the container is formed of paper, strawboard or some similar non-metallic material made in rigid sections so that the parts can be shipped to the user knocked down. By employing paper of great rigidity, a light yet strong body is provided and onewhlch will be uniform in weight'for all containers of the same size and shape. Simple means are also provided for assemblin the sections together and fastening in the ends without. the use of any special tools or implements. This latter feature is accomplished by employi g a locking strip of novel form which serves to unite the sections of the body together, fasten in the heads and provide strengthening stay members for the container.

The invention consists in the novel parts, combinations of parts and details of construction of the knockdown container hereinafter more particularly described and then specified in the claim.

In the accompanying drawings, Figure 1 is a side elevation and partial section of a knockdown container constructed in accordance with this invention in one of its forms. Fig. 2 is an enlarged horizontal section of the same taken on the line 2-2 Fig. l and looking upward in the direction ofthe arrows. Fig. 3 is a fragmentary cross-section taken on the line 33 Fig. 2. Fig. 4 is a perspective view of the preferred form oflocking strip.

The invention is illustrated and will be described herein as applied to a keg or barrel, the body portion of which is formed of a plurality of duplicate sections 1. Each section comprises a panel of straw-board, paper or some similar paper-like material formed in any suitable or desirable manner. A preferred manner of forming these sections is by forming a cylinder of a number of layers of paper superimposed on each other, preferably by spinning, and compressed into a very solid mass to any desired thickness, the various layers being united by suitable cement, glue or other adhesive whereby a very rigid wall is attained. After the cylinder is formed it is cut longitudinally into any desired number of segments to form the body sections 1. By following this method it is assured that the sections will at all times retain their shape and will exactly mate up to form a perfect cylindrical body. The specific manner of form'- ing the cylinder or the separate sections forms no part of this invention and further description will be dispensed with.

2 indicates the locking member for joiningthe separate sections 1 together. Said member is preferably made up from a single strip of metal formed into an ll-shape in cross-section. The l-shap'e is formed by bending each side of the metal longitudinally back upon itself to form flanges 3 and then at right angles thereto to form the web Patented llllar. 30, .Wllfi.

In this manner the v ra'wedges of the paper-sections I'are pro- 'tected against tearing-or mutiliation:

Preferably the band 7 is provided with an inwardl pprojectingg. flange which rests on the end to the bodyio protect the raw edge of the paper against" mutilation; 1 W vThe heads for-the container, one being provided at each end of the body, may be of any desired construction,. the one herein shown comprising a .paper disk 9 fo'rming. the main closure-0f the head, said disk being seated andv heldin an annular, metal -rim 10in any suitable manner. The metal rim 10 is also provided with a flange 11 which seats on the end of the body of the container. g
